1-Bit Massive MIMO Transmission: Embracing Interference with Symbol-Level Precoding
Ang Li, Christos Masouros, A. Lee Swindlehurst +1
The deployment of large-scale antenna arrays for cellular base stations (BSs), termed as `Massive MIMO', has been a key enabler for meeting the ever-increasing capacity requirement…
Symbol-Level Precoding Made Practical for Multi-Level Modulations via Block-Level Rescaling
Ang Li, Fan Liu, Xuewen Liao +2
In this paper, we propose an interference exploitation symbol-level precoding (SLP) method for multi-level modulations via an in-block power allocation scheme to greatly reduce the…
Reconfigurable Intelligent Surface (RIS)-Enhanced Two-Way OFDM Communications
Chandan Pradhan, Ang Li, Lingyang Song +3
In this paper, we focus on the reconfigurable intelligent surface (RIS)-enhanced two-way device-to-device (D2D) multi-pair orthogonal-frequency-division-multiplexing (OFDM) communi…
Near-Optimal Interference Exploitation 1-Bit Massive MIMO Precoding via Partial Branch-and-Bound
Ang Li, Fan Liu, Christos Masouros +2
In this paper, we focus on 1-bit precoding for large-scale antenna systems in the downlink based on the concept of constructive interference (CI). By formulating the optimization p…
